Appendix A, Installing Ansible inside WSL

You recommend to install ansible using "pip3 install ansible" command.
This cause the package and its dependencies not yet installed, especially ansible-base package, to be installed under
/home//.local/lib/python3.8/site-packages/, and ansible executable modules, which are part of ansible-base package, to be installed under ./home//.local/bin/.
So if the above path not defined under user's PATH variable, the ansible command wouldn't be found.
On the other hand, if you install ansible using "sudo pip3 install ansible", the packages will be installed under
/usr/local/lib/python3.8/dist-packages and ansible executable files will be installed under /usr/local/bin/ which is always defined in the PATH variable.
So you can recommend either to add ./home//.local/bin/ to PATH or just to install ansible using sudo.
if you want to reproduce the case, please don't forget to remove ./home//.local/bin/ from PATH and uninstall ansible and ansible-base before reinstalling it.
